After connecting and insulating according to the method, the terminal connection part 8'
is again placed between the insulating sheets 6, 7, and by applying heat and pressure to that part from the outside using a heat roller or the like, the film 11 made of hot melt adhesive is melted and the insulating sheets 6, 7 and the conductive sheet are heated and pressed. The foils 8 are bonded together to form a terminal portion 10 to which a lead wire 12 is connected.
なお、この実施例においては長尺の絶縁シートに面ヒー
